Not sure what you mean-the residue is how they work for the lasting killing effect. Perhaps you can rephrase. There are contact sprays that are chemical based with no residual, those are residue free except for perhaps harmless by products after they dry off.
A. Is this information being used to advocate a point of view?
Organic foods are those grown without the use of synthetic fertilizer or pesticides. When these foods are processed, they do not contain additives or preservatives that are found in non-organic foods. Their benefits are that they are free of additives, preservatives, and pesticide residue (unless there are trace amounts that blew on to them from non-organic crops), and are free of GMOs.
Chemical fertilizers and pesticides are not used in organic gardening/farming, though according to USDA guidelines, pesicides can be used in certain situations, so under normal circumstance organically grown foods are chemical free. Also, organic foods are for the most part GMO free, though according to government regulations, they do not have to be totally GMO free. Since synthetic pesticides and chemical fertilizers are not used, the environment is not being harmed. In fact, part of organic growing is building up the soil, so the soil benefits from organic farming.
Yes, blueberries should be washed before freezing to ensure they are clean and free of any dirt or residue.
farmers avoid using pesticides because it is a chemical made in factories. It reduces the fertility of the soil and it also kills useful bacteria already present in the soil.AnswerUS farmers mainly avoid pesticides primarily due to their cost of both purchase and application. If any particular pest is not prevalent enough in the field to pay for the pesticide use, he will not apply it. Also, organic farmers must avoid using non-approved pesticides in order to have their crop be "certified."
Three years is the length of time that soil has to be chemical-free for organic gardening. For example, the National Organic Program and the Organic Council of Ontario respectively provide guidelines and inspections for organic farming in Canada and in the United States. In both countries, organic growers will not receive or sustain certification if their soil tests positively for the presence of antibiotics, chemical fertilizers, genetically modified organisms, irradiation, sewage sludge or synthetic fungicides, herbicides or pesticides in the three years prior to application.
metal residue on surface as a free compound, do not interact as inner sphere or outer sphere to surface. The residue related to access of metal compound after all functional already occupied by adsorption process.
Only residue-free shampoo should be used on dreadlocks.
The aim of organic farming is to ensure that the produce it yields is free from artificial fertilizers, fungicides and pesticides that could harm human, animal or plant health. Also, it is to ensure that the ecosystem as a whole is free from chemical contamination, and to maximize the level of nutrition in produce, which can be lowered when artificial ingredients are added to their cultivation.
No. Everything that has mass and volume is a chemical or a part of a chemical. Chemical free shoe polish would have to be some form of energy.
A new rabbit-safe toy, some extra time spent petting/grooming or some fresh chemical-free grass or clover - make sure you don't pick it from a lawn that has been treated with pesticides, herbicides or fertilizers.
LPG is nothing but a gas free from CO
